Title: Process and apparatus for preventing the raising of dust by motor road vehicles
IPC: B60S1/62
Filed: 1923-03-26
Abstract: 195,958. Bandelier, A. April 8, 1922, [Convention date]. Dust, preventing rising of. - In apparatus for preventing the raising of dust by motor road vehicles, in which jets of atomized water are projected directly on to the ground around each wheel of the vehicle by means of a pump driven by the engine, constantly-operating means are provided for keeping the spraying nozzles free from choking. In the illustrated construction, a cylindrical reservoir a, arranged beneath the drivers' seat, is connected by pipes to U-shaped tubular sprinklers b surrounding the rear half of each of the four wheels. A wheel c<5>, oscillated by contact with the road wheel, serves to rock levers c<2> to which are pivoted needles c passing through the nozzles in the sprinkler tubes b. The jets escape downwards through the annular space between the needles and the wall of the tube, the reciprocation of the needles preventing choking. The pump d forces air into the reservoir to expel the water to the sprinklers when a delivery valve a<3>, within reach of the driver, is opened. A safety valve operates to cut off the drive to the pump when the pressure in the reservoir rises to a predetermined amount.

Abstract: 835,290. Machine-tool details. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 25, 1958 [March 26, 1957], No. 9838/57. Class 83 (3). A power-operated indexing-lathe for boring, drilling, milling &c., machine tools comprises a pair of double-acting pressure-fluid operated pistons, one controlling axial movement of an index plate and turntable off the supporting bed, whilst the other controls the rotation through a predetermined angle, the operation of the two pistons being under control of the index-table mechanism after an index movement has been initiated. The indexing table 1, Fig. 2, is rotatably supported through a bearing 2 on a vertical pin 3, which is axially movable but held against rotation by a pin 15. The pin is supported in a boss 8 carried by a frame 7, and is moved to lift the table away from the frame by a screw portion 5 engaged by a rotatable nut 6 supported on a thrust bearing 44. When the pin is drawn down by the nut, the table is clamped and supported against the frame 7. A gear 11, rotated about the boss 8, has a projecting pin 12 which engages the table to effect the indexing movement. The gear 11 is rotated by a gear train 36 of pick-off gears rotated by a rack 16, Fig. 1, secured to an airoperated piston-and-cylinder device 26. A second piston-and-cylinder device 39, anchored by a pin 41 to the frame, rotates a lever 43 connected to the clamping and raising nut 6. This lever is connected to a rotatable cam ring 57, arranged about the boss 8, which has a cam slot to declutch the gear drive to the take on return movement of the rack 16. The lever 43 carries at its outer end a cam piece 47 which is adapted to raise a locking plunger 48 against a retracting spring 51 to engage a series of index holes in the table 1. The pin, when moved out of engagement by the spring, operates an air valve 56. A further cam part 67 on the cam ring 57 operates, through a roller 68 and lever 69, a further air valve 66. The sequence of indexing movements is started by depressing a plunger 74, Fig. 1, after which the movements take place automatically until the table is again reclamped. This plunger may be operated by a part of a machine tool carrying the table. The piston-and-cylinder devices may be operated hydraulically, and the Specification states that electrically operated valves may replace the mechanically operated valves described.

Abstract: 551,791. Electricity supply. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET., and EGER, L. Aug. 6, 1941, No. 9982. [Class 38 (iv)] Synchronizing.-Two, relays 13, 14 are selectively operated according to the order in which relays 7, 8 operate during the synchronizing of two circuits. 1, 2. The'relays 7, 8 close their contacts 7a, 8a when insufficiently energized, and are subject respectively to rectified beat currents between transformers 4, 5, and 4, 6 which beats change their relative timing as synchronism is passed through. The mutually interlocked relays 13, 14 respectively energize self-locking relays 15, 16 which release only when the order of operation of relays 7, 8 changes. Each energizes'respectively relays 17, 18 which control contactors 27, 28 starting a speed adjusting motor or motors 30 in the appropriate direction. The relays 13, 14 also energize a relay 19 which maintains the relays 17, 18 and the motor in operation for a fixed period determined by a timing relay 20 which it energizes on closing. The relay 19 also operates a timing relay 21 which determines the period of closure of relay 20 and renders relays 17, 19 temporarily unresponsive to relays 7, 8. The intervals between operations of the motor depend upon the'time between de-energization of relay 22 and the succeeding impulse due to relay 7 or 8 and increase with the beat period ; when these intervals exceed a given value relay 23 closes resulting in operation of a time relay 25 which causes periodic operation of the motor for fixed periods at fixed intervals.
